All the expert forecasts predict that container throughput will double over the next ten years. If Bremerhaven – a seaport in the north of Germany – wishes to keep pace with these developments, the port facilities have to grow. In order to provide the urgently required space, bremenports had already extended the quay by 340 m a few years ago. Construction phase Container Terminal (CT) 3a, however, was just the prelude to the much more difficult project Container Terminal 4, which will create four new berths for mega container vessels. The terminal construction project will extend the riverside quay by 1681 m to a total usable length of 4720 m - the longest riverside quay in the world.
